Applications of SuperAurum ™
™
Since SuperAurum has a high HDT of 752°F (400°C), it can replace
other polyimides, ceramics, and metals. XCL3030 is a representative
grade as a wear and friction material, offering

®
1. Limit PV exceeding that of Aurum and the capability of 1.3 times
®
as great as Aurum grade JCL3030
2. Much higher temperature resistance up to 572°F (300°C) as a bear-
ing material

Therefore, it can be used for applications where PEEK and Aurum ®
cannot be used. Application examples include

1. LCD and semiconductor handling parts
2. Carriers such as wafer carriers, HDD carriers, and LCD carriers
3. Industrial machinery, electrical insulators for high-pressure usage
4. Oil exploration parts
5. Aircraft and aerospace
6. Chip seals and piston rings
